If you own a 3M™ Adflo™ PAPR system, it is important to properly care for it to ensure its longevity and effective performance. Here are some frequently asked questions about caring for your Adflo™ system:
How should I clean my Adflo™ system?
You should clean the exterior of the Adflo™ unit with a clean, damp cloth. Make sure to remove the particle filter and prefilter before cleaning, and do not submerge the unit in water. Allow the unit to dry completely before reassembling the filters.
How often should I replace the particle filter and prefilter?
The frequency of filter replacement depends on your specific work environment and usage. However, a general guideline is to replace the particle filter and prefilter at least once every 6 months, or when they appear dirty or damaged.
How should I store my Adflo™ system when not in use?
Store your Adflo™ system in a clean, dry area that is free from extreme temperatures and direct sunlight. Make sure to store the unit with the particle filter and prefilter removed to prevent moisture buildup.
How do I know when it’s time to replace the battery?
The Adflo™ system will display a low battery warning when it’s time to replace the battery. Make sure to replace the battery with a genuine 3M™ Adflo™ battery to ensure optimal performance.
How do I troubleshoot my Adflo™ system if it’s not working properly?
If your Adflo™ system is not working properly, refer to the troubleshooting section of the user manual for step-by-step instructions. If the issue persists, contact 3M technical support for assistance.
